How would you compare the pro/con of the A1/A2 vs. Canon's Pro1 vs, Sony 828?

I am a Minolta 7Hi owner who's been a little disappointed with indoor shots (some blurred and most darker than I'd like as well as limited flash range, either too bight on the subject and dark everywhere else or just plain too dark)

We're also not totally pleased with the Autofocus ability of the 7Hi, seems sometimes shots are blurry and we don't know why as we've grown to concentrate on the focus element and still some shots are blurred.

Any custom setting recommendations for the 7Hi indoors would be appreciated.
As we are learning, we shoot primarily in Auto, Aper. pri, or Shut pri. modes.

Would upgrading to the A1 or 828 or Pro1 solve any of these problems (especially for my wife who's nearly a 100% P/S user.

We really like the manual zoom and feel we took much better pictures with our lowly Nikon N60 slr in our film days.

The 7Hi appears to excel for us outdoors, but indoors (most of our kid shots) struggles.

I second that... they are all pretty much the same with the A2 having the most features as well as a usable RAW mode (if you're into it) unlike all the others. It is also the most SLR like with a zoom and a manual focusing ring which could manually overide the AF after it locks just like any ultrasonic lens.
